It is a powerful analgesic agent at well below full anesthetic concentrations. [ 18 ] [ 56 ] [ 57 ] [ 58 ] [ 37 ] Because of its low volatility and very high boiling point (104.8 °C at 1 atmosphere), methoxyflurane has a low vapor pressure at ambient temperature and atmospheric pressure .
Initially CO 2 was thought to work through anoxia, but in the early 1900, increased CO 2 in the lung showed a dramatic increase oxygenation of the brain disproving the anoxia argument. [11] Prior to the development of modern anesthetics, CO 2 was used extensively by psychiatrists in a treatment called carbon dioxide inhalation therapy.
It is available in the form of an inhaler containing 50 mg total per inhaler and delivering between 0.04 and 0.15 mg of the drug per inhalation. [2] Inhalers with a total of 113 mg levmetamfetamine were previously marketed in the United States, but the total amount was eventually reduced to 50 mg. [ 2 ]
An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications.

MDI canister and actuator components from H&T Presspart. A metered-dose inhaler consists of three major components: the canister, which is produced in aluminum or stainless steel by means of deep drawing, where the formulation resides; the metering valve, which allows a metered quantity of the formulation to be dispensed with each actuation; and an actuator (or mouthpiece) which enables the ...
Most DPIs rely on the force of patient inhalation to entrain powder from the device and subsequently break-up the powder into particles that are small enough to reach the lungs. [2] For this reason, insufficient patient inhalation flow rates may lead to reduced dose delivery and incomplete deaggregation of the powder, leading to unsatisfactory ...
